Putting arguments into standard form

I can understand the basic standard form of an argument when it is given to me, but when I see an argument without a second premis I dont understand it. My teacher is not very good at explaining and will not even recommend a good book for me to read to help understand. This is my last hope to understand these examples before the test tommorow, so if someone can please help.

For example I was given the following questions as a study guide:

A. Women live longer than men, on the average. So, you will probably live longer than your husband!

This is what I think:

P1: Women Live longer than men
P2: Women live longer than men on average, so you will probably live longer than your husband.
Conclusion: You will live longer than your husband.

Am I doing this correctly? See there was no clear second premise so I made my own, can you do that?

B. "Women Have rights", said the bullfight association President. "But women shouldn't fight bulls because a bullfighter is and should be a man."

p1: Women shouldn't fight bulls
p2: because a bullfighter is and should be a man
c: women have rights

See that just doesnt make sense to me.

C: Subliminal advertising is quite common. Why? Hundreds of studies have shown that subliminal persuasion works. You end up buying things you neither want or need; like a singing , flipping rubber fish on a board.

Im assuming the the Conclusion is that "subliminal advertising is quite common" and that the first premise is that "hundreds of studies have shown that subliminal persuasion works." Now I dont see the second premise, is that because "you end up buying....fish on a board"

D. It would be foolish to permist the sale of marijuana to seriously ill people on the recommendation of their physicians. That just opens the floodgates to the complete legalization of that dangerous drug.

I dont even know where to start on this one.

I think a problem is he is teaching in a form like this
P->Q
P->R
= Q->R
So I am looking for a way to put these arguments into that form and am not seeing it.
